As a Clean Energy Leader, New Holland has been pioneering the use of bio-diesel in agricultural machinery since 2006, and currently is researching the most advanced technologies. It developed the NH2TM tractor, the first to use hydrogen fuel cells, and the Energy Independent Farm concept, exploring ways to enable farmers to reach zero emissions and energy independence in the future.
In the meantime, Tier IVA emissions regulations will become a legal requirement in 2011 for medium- and heavy-duty engines above 174 hp (130 kW).
“We believe that a one size fits all approach just won’t work in modern farming,” explained Pierre Lahutte, director of Global Marketing and Communication of New Holland Agriculture. “We are committed to integrating the best available engine technology for every machine and operation.”
To achieve these goals, New Holland has adopted SCR (Selective Catalytic Reduction) technology for machines with engines above 100 hp (74.5 kW) and CEGR (Cooled Exhaust Gas Recirculation), for engines below 100 hp.
These solutions have been developed in partnership with Fiat Powertrain Technologies. It has already produced more than 100,000 Cursor and Nef engines that effectively use SCR technology. Throughout this process, the technology has been continually developed and refined. This has resulted in a reduction in operating and maintenance costs, while increasing productivity and meeting emission requirements at a competitive price, according to the manufacturer.
SCR is an after-treatment system that is separate from the main engine function and does not compromise horsepower or torque. The SCR system uses a catalyst that treats the nitrogen oxides contained in the exhaust gas with an odorless mixture of chemical urea and purified water, transforming them into harmless water and nitrogen. It is easy to use and simply requires the operator to fill the additive tank.
“SCR will be further developed to guarantee our customers the most reliable, cost-effective and state-of-the-art products, when future, ever more stringent emission regulations are introduced for the agricultural industry,” said Lahutte. “By using SCR technology beginning in 2011, New Holland has invested in research and development now that will be invaluable in helping us to achieve final Tier IVB requirements.”
